This tutorial illustrates how to model an earphone using surfacing methods. Since a lot of persons doesn't know about surfacing model therefore i tried to perform every function step by step. If you have any problem struggling with that even after my efforts, just let me know. I will help you as much as I can.
1. Step 1
  
  Start Solidworks in Part mode. Select front plane and then sketch.
2. Step 2
  
  Draw entity using splines like this one. For this sketch i have used two spline and a centre line along right plane. The two splines are having tangent relation.
3. Step 3
  
  Now select revolve surface under surfaces tab. Revolve the profile along the centre line.
4. Step 4
  
  Under surfaces tab select Reference geometry >> plane. Now select Right plane as the first reference and offset it by considerable distance.
5. Step 5
  
  Now select plane1 and then sketch.
6. Step 6
  
  Draw a circle like this one.
7. Step 7
  
  Under sufaces tab click Extruded surface.
8. Step 8
  
  Extrude it in both direction with a considerable distance.
9. Step 9
  
  Now select front plane and then sketch.
10. Step 10
  
  Draw two spline cutting the surfaces.
11. Step 11
  
  Under surfaces tab select trim surfaces.
12. Step 12
  
  Select the surfaces under the splines and remove them.
13. Step 13
  
  Under surfaces tab select lofted surface.
14. Step 14
  
  Select both edges.
15. Step 15
  
  Under Start/End constraints change start and end constraint to tangency to face. Click OK.
16. Step 16
  
  We have basic shape of the earphone. I have decreased the radius of the extruded surface Because it was a little larger.
17. Step 17
  
  Select section view in standard views.
18. Step 18
  
  Select front plane for section and click OK.
19. Step 19
  
  Under surfaces tab select offset surface.
20. Step 20
  
  Select the top face and change the distance to minimum i.e. about 1.5mm in my case.
21. Step 21
  
  Now select Top plane and then sketch.
22. Step 22
  
  Draw a circle.
23. Step 23
  
  Under surfaces tab select trim surfaces.
24. Step 24
  
  Trim the inner portion of the top-most face.
25. Step 25
  
  Again top plane and then sketch.
26. Step 26
  
  This time draw a circle considerably smaller than last one.
27. Step 27
  
  Select trim surface under surfaces tab.
28. Step 28
  
  Select the outer portion of the offsetted surface.
29. Step 29
  
  Click OK and the area is trimmed.
30. Step 30
  
  Under surfaces tab select boundary surface.
31. Step 31
  
  Select both edges.
32. Step 32
  
  Select tangency to face for both edges.
33. Step 33
  
  Click OK.
34. Step 34
  
  Now under surfaces or feature tab select reference geometry and then axis.
35. Step 35
  
  Select top plane and origin. This will create an axis perpendicular to top plane and passing through origin.
36. Step 36
  
  Now select top plane and then sketch.
37. Step 37
  
  Make a circle for hole.
38. Step 38
  
  Now click linear sketch pattern in sketch tab.
39. Step 39
  
  Select the circle to entity to pattern.
40. Step 40
  
  Adjust the distance and increase the number of instances.
41. Step 41
  
  Now select circular sketch pattern.
42. Step 42
  
  Now select the 2nd circle to pattern.
43. Step 43
  
  Repeat the same step for other circles increasing the number of instances each time.
44. Step 44
  
  Under surface tab select trim surface.
45. Step 45
  
  Now select keep selection.
46. Step 46
  
  Select the excluded surface of holes.
47. Step 47
  
  Click OK and the surface is trimmed.
48. Step 48
  
  Now select top plane and then sketch.
49. Step 49
  
  Use slot tool to make 2 slots.
50. Step 50
  
  Now select trim surface in surface tab and select remove selection. Select the surface bounded in slots and click OK.
51. Step 51
  
  Now we have the space for the air.
52. Step 52
  
  Select knit surface under surface tab.
53. Step 53
  
  Select all surfaces one by one and then click OK.
54. Step 54

55. Step 55
  
  Select the surface. It will select Knit surface feature. Change the thicken distance to 1mm and outside direction. Click OK.
56. Step 56
  
  Now we have solid body of the earphone. We will now seperate the bodies.
57. Step 57
  
  Select top plane and then sketch.
58. Step 58
  
  Change view to hidden with shaded line.
59. Step 59
  
  Offset the edge by 0.50mm and then draw two straight line horizontally. Trim other entities.
60. Step 60
  
  Select revolved surface in surface tab.
61. Step 61
  
  Select axis1 and click OK.
62. Step 62
  
  Go to insert menu then feautres >> split.
63. Step 63
  
  Select the revolved surface as the trim tool and click cut part.
64. Step 64
  
  Now check both the bodies and click OK. This feature will generate two split bodies by the revolved surface.
65. Step 65
  
  Now hide the revolved surface.
66. Step 66
  
  Again select section view about front plane in standard view toolbar.
67. Step 67
  
  Select reference geometry and then plane under surface or features tab.
68. Step 68
  
  Select top plane and then offset it by a distance so that it will lie in the upper body.
69. Step 69
  
  Select the plane2 and then sketch.
70. Step 70
  
  Draw a circle larger than the region bounded by the holes.
71. Step 71
  
  Under features tab click extruded boss/base feature.
72. Step 72
  
  Under direction1 select up to body.
73. Step 73
  
  Select the upper body and enable thin feature by a distance of 0.50mm. Click OK.
74. Step 74
  
  Now we have the body for the speaker of ear phone.
75. Step 75
  
  Now click file save.
76. Step 76
  
  Enter any file name for the part document. I entered earphone for myself.
77. Step 77
  
  After saving part click insert>>feature and then split.
78. Step 78
  
  Again select revolved surface2 from the surface bodies under tree view and click cut part.
79. Step 79
  
  Double click the cut body1 and save it.
80. Step 80
  
  Repeat the same step for the other body and click OK.
81. Step 81

  Right click the upper body and select float.
86. Step 86
  
  Move it and then rotate it to have a better view.
87. Step 87
